Anyone else notice a certain noise when riding or accelerating while not in gear? Such as if rolling down a hill. It sounds like what a tire sounds like when it has a flat spot, but the sound disappears when the car is in gear. I don't believe it is related to the engine, nor tires.

 

axles?

 

my car doesnt do that.
but my neighbors does and idk what it is.
it kinda sounds drivetrain related.
maybe a bearing or something.

 

is your car still under warranty?if so just bring it in. maybe its a bearing in the trans

 

I think u have throw out bearing issue, have ur flywheel checked out , i had that problem with bmw 325 i had a few years back....
